SLIDING DISC VALVES • OVERVIEWSVC The SVC-type valve is a sliding disc valve with a ceramic sealing system for open/close function and control tasks, for use in highly corrosive and extremely abrasive media. It is designed for extreme conditions, where either high switching frequencies and a long service life are required, or where severe abrasion occurs in the control position but dead space cannot be permitted inside the valve.

The functional principle is based on four floating ceramic discs that seal against each other. The 2 middle discs shift linearly against each other in opposite directions.Different geometric shapes of disc apertures permit specific control characteristics. The two outer discs are stationary.

The medium only comes into contact with ceramic components and seals, so that special materials are normally not required for the housing.

SSC The SCC-type valve is a sliding disc valve with a ceramic sealing system for open/close function and control tasks, for use in highly corrosive and extremely abrasive media. It is designed for extreme conditions, where either high switching frequencies and a long service life are required, or where severe abrasion occurs in the control position but dead space cannot be permitted inside the valve.

The functional principle is based on three floating ceramic discs that seal against each other. The middle disc shifts linearly.Different geometric shapes of disc apertures permit specific control characteristics. The two outer discs are stationary. Springs are used to compress the sealing system.

The medium only comes into contact with ceramic components and seals, so that special materials are not normally required for the housing.

SDL The SDL-type valve is a sliding disc valve with a ceramic sealing system for open/close function, for use in highly corrosive and abrasive media.

The valve is designed for extreme conditions, where high switching frequencies and a long service life are required, but dead space cannot be permitted inside the valve.Control functions can be realised using a switching frequency control system.

The medium comes into contact not only with the ceramic discs, but also with housing parts and seals. Alongside the standard solutions, other material combinations are possible, depending on operating conditions.

This slide valve type is designed for very small volume flow rates in the nominal width range from below 1 mm up to 10 mm. Pressures of up to 250 bar / 3600 psi are permitted here.

DESIGN:

Wear-resistant, corrosion as well as high-tempera-ture resistant design, modular construction, thus an optimum adjustment to the operating conditions.

CERAMIC MATERIALSPROPERTIES AND DISTINCTIVE FEATURES

CORROSION RESISTANCECompared to other materials, the corrosion resist-ance of the ceramic materials is significantly more higher and can be used in broader range on corro-sive applications. Ceramics are completely resistant against the majority of solvents. Aqueous brines are generally no problem. The ceramics used are highly resistant against the majority of acids up to relatively high temperatures. Nevertheless, there are large differences that are to be observed. All oxidic ceramic materials are not resistant against fluorides for example. Some materials (e.g. Y-PSZ) are sensi-tive to water vapour (not hydrothermally resistant). It must be observed that mixtures of reagents gener-ally react differently than the individual components.

PRESSURE RESISTANCE AND FLEXURAL STRENGTHIn contrast to metals, the mechanical strength properties of ceramic materials are different when bent, when under load and when under pressure. While the pressure resistance in almost all dense ceramics is many times higher than that of metals, the tensile and flexural strength must be closely observed.

Even if the comparison of the strength values of metals and ceramics is problematic, it does demon-strate the difference in size.

CERAMIC MATERIALSAl2O3 Aluminium oxideZrO2 Zirconium dioxideSSiC Silicon carbideSi3N4 Silicon nitride

DENSITYWeight is also generally saved when ceramics are used as these materials have a density up to 78 % less than that of hard metal / 60 % less than that of stainless steel.

HARDNESS AND WEAR RESISTANCEThe wear resistance of components is significantly influenced by the respective type of load. Thanks to their extremely high hardness, ceramic materials have a wear resistance against friction that is many times higher than metals.The mixture of loads that often occur in practice such as friction wear, radiation wear and impact wear as well as cavitations are generally absorbed better by ceramic components than metal com-ponents. All direct impact loads required closer observation.

THERMO SHOCK RESISTANCECeramic components maintain their shape and strength as well as their further physical character-istics up to extremely high temperatures. In con-trast to the maximum operating temperature, the thermo shock resistance must be closely observed. In addition to the material dependency, the thermo shock resistance is also highly dependent upon the geometry. Simple geometric shapes such as pipes are less sensitive than such parts that have highly differing wall thicknesses for example.

FUNCTION: TYPICAL APPLICATION AREAS:TA-LUFT SEALINGUNIVERSAL SEALING KITS FOR STEMS

The strict regulations of the current TA-Luft place the highest of demands on the stem shaft seals of valves, especially with regard to fugitive emissions. The TA-Luft sealing kits cover the majority of appli-cations, especially in the chemical and petrochemi-cal sector and are suitable for use in new valves or to retrofit existing valves.

Available TA-Luft sealing kits: BuraTAL® T3 9650/T3Application limitsTemperature: -10 °C to +250 °C / +14 °F to +482 °FPressure: 63 bar / 914 psiChemical resistance: pH value 1-13BuraTAL® T3 9650/T1Application limitsTemperature: -40 °C to +280 °C / -40 °F to +536 °FPressure: 40 bar / 580 psiChemical resistance: pH value 1-14BuraTAL® HT 9650/HTApplication limitsTemperature: -200 °C to +400 °C / -328 °F to +752 °FPressure: 300 bar / 4350 psiChemical resistance: pH value 1-13

These sealing kits cover the required leakage values according to the VDI directives across the whole temperature range. This means that the leakage values of 10-4 are not reached at temperatures below 250 °C / 482 °F and 10-2 are not reached at temperatures above 250 °C / 482 °F on the seal. The checking of this is assumed by a spring application system de-signed especially for this application. This so-called live loading system ensures the constant surface pressure on the sealing kits that consists of a combination of diverse packing rings as a chamber, sealing rings and flat seal as intermediate layers. The live loading system is designed according to the operating temperature and operating pressure (spring package) and set according to the assembly directive (checking gap between the spring sleeve and the stuffing box gland).

The requested control behaviour of the slide valve is determined by the bore geometry of the stroke disc. The opening cross-section is changed by the linear movement of the stroke disc affecting the flow. The control behaviours are possible linearly and with equal percentage.

Properties:• Low overall height• High regulating forces at a high setting speed• Low friction• Various bench ranges • Reversal of the effective direction without special tools • Permitted operating temperature -60 to +120 °C• Direct attachment of accessories • Type 3277 with a protected travel linkage

DesignsActuator areas 175, 240, 350, 355, 700 or 750 cm² for the direct attachment of accessories, optional corrosion-resistant design in 1.4301

Principle of operationAt the actuator area, the actuating pressure gene-rates a force balanced by the springs. The nominal stroke is determined by the number of springs and their preload. The stroke is proportional to the actuating pressure.Its effective direction depends on the mounting position of the springs, and the actuating pressure connection.A coupling connects the drive rod with the stroke rod of the slide valve.

Effective direction• Drive rod extending by spring force (FA)• Drive rod retracting by spring force (FE)

CERAMIC COMPONENTSCera System develops and produces customer-specific ceramic preci-sion components in small batch sizes through to series production for the most diverse areas of application. Focal points are sealing and control discs for air conditioning, sanitary fittings as well as many other applications. Ceramic components for the sensor, food engineer-ing and building services sectors round off our portfolio.

CERAMIC HOSESCera System supplies wear resistant flexible solutions. Ceramic hoses manufactured by Cera System can be used everywhere where hoses regularly wear and must be replaced. The hose consists of ceramic rings that are vulcanised together with special reinforced rub-ber materials. Pressures of up to 10 bar / 145 psi are permitted.

BALL VALVESCera System offers wear and corrosion resistant ball valves for open / close and control function. The use of ceramic lined valves is sensible in all cases where standard valves reach their limits (abrasion, corro-sion, temperature and pressure). A large range of metallic and ceramic materials permits solutions for almost all industrial sectors. Special applications are solved in close cooperation with our customers.

PIPE WEAR PROTECTIONCera System offers wear resistant pipe elbows, Y and T parts as well as other shaped pieces. The most diverse of ceramics are used. The ceramic is solid (wall thick-ness approx. 6 mm (¼˝ ) ). All solutions are nominal size conformant, they can be assembled problem-free without having to adjust the pipelines. The clear width corresponds to the flange connection. Our speciality: the ceramic pipe elbows are actually curved (no ap-position of straight sections).

SLIDING DISC VALVECera System offers wear and corrosion resistant sliding disc valves for open / close and control function. With this type of construction just the ceramic are wetted by the fluid. It is therefore suitable for highly corrosive media. Further advantages: Excellent control of small amounts containing solids - completely cavity free. The slide valve is available from DN 2 (5/6˝ ) up to DN 50 (2˝ ).

CERAMIC SYSTEM SOLUTIONSCera System offers system solutions with ceramic com-ponents. In-house development and sales engineers ensure for the complete design of ceramic systems and create economical, customer-specific complete solu-tions all over the world. Product developments in the coal gasification and photovoltaic sector are only examples of numerous other industry-specific applications.
